The gdb trace is useless without the debugging symbols, install them and try again.

A gdb trace does not help for debugging performance problems anyway.

"strace" would at least say what qBittorrent is actually doing.

With much emphasis on

I am also seeing this in Ubuntu 10.10 x64 using qBT 2.6.5+svn.r5225-1~maverick.

I cannot reproduce the issue although I'm using Ubuntu 10.10 x64 as well.

What do you mean exactly by "The GUI hangs"? Is it unresponsive when you try to do something? Is CPU usage abnormally high when this happens? How about disk activity?

Are you saving to a unusual location? for example, an encrypted drive or folder, A network drive, a Non-Linux file system (e.g. NTFS). There are to be something different with your configuration or I would get way more bug reports about this.

@SDERAWI: Your state(/etc/localtime) messages seem to be caused by the fact that your timezone is not set.

Could you try to do the following?
$ export TZ=:/etc/localtime
Check that localtime file is actually located in /etc on your distribution

then
$ strace qbittorrent

This should silent the stat(localtime) messages. However, this may not be the cause of the hang : we'll see.

Regarding my setup , I did not do anything different (Save location , encrypted drive etc.) between 2.6.1 and 2.6.2 - 2.6.5.

But actually the CPU becomes 100% most of the time but not always.

And regarding the GUI hangs = I can not click on anything , not even the Icon in the panel, It is like the program is not there . And If I do a reload window manager from Fusion-Icon, Qbittorrent's Icon disappears from the panel until all the downloads finish and the GUI becomes responsive again
